Confirmed, will forward it to devs.

Improvements are scheduled, but since source seems to be of external nature, we're working on more thorough overhaul including new features mentioned in an update.

Will test later in the day, thank you for info !

We tried to pile those updates for a larger release and seems like some of them made it. More recent ones didnt, look for a changelog posted by Rudel. We will ask ED to add them as well the the main changelog.

Yes, we're working on a bigger package rather than small updates. Some fixes were released, but major upgrade will arrive later. We're still working on some of the stuff. We're intending to release this evening a development update if I can finish it. It's going to touch future modules but also, and most importantly, fixes and improvements you're looking for for CE2 and MiG-21bis.

That goes without saying :)

We're preparing news. Including something on F-8. Dont worry ;)

I will forward this to our artist for a review. Thank you for the report !

I think racks are present in game by default and factored into aircraft drag.

Which real life data if I may ? I'm not as familiar with Dora, so I wont be picking data on that one, but P-51 performance is modeled after this report: http://www.wwiiaircraftperformance.org/mustang/p51d-15342.html I have replicated a military power run on deck as that eliminates all the variables and need to recalculate indicated and true air speed. At 3000 RPM, 61" MAP, coolant flaps auto and ICAO Standard Atmosphere aircraft reaches 363-364 mph on deck. Which matches real life data perfectly. Max speed that could be achieved at 67" MAP (War Emergency Power) was 375 mph. I have not tested that, if I find time today I can try. But based on the rule of thumb I'm expecting it to turn out to be the same as in given document. And btw. the above real life data give P-51D 603.5 km/h as thats to what 375 mph translates to. So yes, D-9 could've been faster by less than 10 km/h. But those 10 km/h can easily be mitigated by ones ability or inability to fly aircraft. Its easier to fly P-51D clean due to ability to trim all three control surfaces. Kurt Tank did not provide that for Dora (or Anton) which makes flying a bit harder.

It's not about respect but politeness. You dont have to respect the other person, to be polite to him. As for the disagreement. You brought up the point about changes in P-51D FM. That you think it was beefed up and you have strong evidence for that. And when others disagreed, you call them whiners. Present the evidence and lets talk this over because you havent addressed yet data I posted on previous page about ingame recordings made by Yoyo 8 years ago. And its easy enough to replicate this top speed test. 61" MAP, 3000 RPM and Auto radiators. I usually test in ICAO standard atmosphere but thats up to you.

You know amazingme, being nice to other people doesnt cost you anything but it sure makes you look better ;) Yoyo stated some time ago that there will be overhaul to engine thermodynamics. I think its best to ask him if he knows anything about it.

Which is actually why I asked about that wing and airfoil design :)

Well, did you actually look into the airfoils used by Mitsubishi so you arrived at that conclusion or what is the exact basis of your conclusion ?

Well, did anybody actually try to compare P-51 to the data that Yoyo actually used as a reference in his own P-51 FM and results of his FM vs real data: Source: https://forums.eagle.ru/showpost.php?p=1577405&postcount=7 I've done those tests a few times, for another reason than this discussion, but this can help us know how P-51 compares now to what Yoyo created 8 years ago. So 61" MAP, 3000 RPM, radiators auto. I could get pretty much every time to ~363-364 mph on deck. To me nothing has changed when it comes to P-51 top speed. Now that user can manipulate with radiator and RPM ... well, in real life it was possible as well. But risky and I'd not recommend to do it irl or in game. Radiator flaps trick is good for pursuit but any maneuvering and your engine is done. As for the Dora. I dont know about the performance decrease in numbers. Did not carry any tests so wont comment on that. But from purely subjective point of view of my daily flying. Dora struggles with low speed acceleration. On the ground it requires significant throttle operation to get it running, last night I felt like someone glued my airplane to the ground. I also have some trouble with engine failure due to overheat. I always warm up prior to take off to reach minimum of 50 deg C on oil and only than taxi to the runway. Had a few accidents when shortly after take-off engine started running rough, some weird sound could be heard and I felt loss of power as I was unable to maintain 400 km/h in level flight at 1.4 - 1.5 Ata. After landing and pulling back the throttle to idle engine was stuck in some limbo of starting and stopping. Similar to what happens when you energize the started too shortly. Than it also can get stuck in that mode and you need to get a new airplane. But in flight problem was clearly a matter of overheating. Interestingly after that cowl flaps stopped being operational and oil temp never decreased, even when Ata was lowered and nose dropped to increase the speed. If I had more time Id investigate engine cooling / thermodynamics. Maybe those are my errors, maybe there is an issue. But despite my issues so far it did not stop me from being competitive online in Dora. This aircraft is extremely capable and a lot more enjoyable than the 109. For one it requires a lot more skill and tactical planning than K-4.

That is not correct. A6M was not draggy at all if you compare it to any other design with radial engine or even some with inline engines (early 109s like E come to mind). If it was, 800 HP engine would not permit it to cross 500 km/h requirement stipulated by the IJN. Jiro Horikoshi and entire Mitsubishi team put special attention to making design aerodynamically optimized, and that meant not only the wing design and selected airfoil but also propeller hub, cowling and canopy design. The calculated drag coefficient (Cd0) based on flight results for A6M1 (so with Zuisei 13 engine, prototype) was 0.0200, while for A6M3 (with Sakae 21 engine) was 0.0215. I somewhere have Jiro Horikoshi memoirs, might find more in that over the weekend. For an aircraft with radial engine it's very good.

The weight was directly corresponding to engine power. Zero was fairly large aircraft and it could've been a bit heavier (it got heavier during production) but without adequate engine it would make achieving prescribed by the Japanese Navy requirements impossible to achieve. So I think lower top speed was primarily limited by the engine power, though Horikoshi made a valid point as to show any other combat aircraft produced at a time that with engine power roughly equal to 800 - 820 HP could break the 500 km/h top speed. Previous generation of Japanese designs had speeds more in range of 400 - 450 km/h, so in comparison Zero wasnt as slow :)

I'm not sure what we can do since we could not reproduce the issue with complete shutdown. After switch there was a split second problem but after that it was smooth, engine still running. I dont think that is possible. That would require simultaneous control over the aircraft systems by both users.

I have it somewhat confirmed ? It seems that when two people fly in the same aircraft, as you pass controls, person that looses it for a split second can see the propeller stop and all gauges flicker. However we did not experience complete engine seizure. Only this very short stoppage visible to one person. In any event, I brought it to devs attention.

Will check this out and come back to you Flagada.

We did not have those issues with radar performance until some time ago. If this is affecting other modules than it could be some issue of more general nature. Still, I dont want to speculate but will forward your input ;)

We're both aware and working on it for a while now. Since there was nothing to further say about that, I did not comment. Once I know that fix is coming, I will bring the news ;)

The S-24 crash issue is already being worked on. I've tested files which fixed it for me. Hope that they can be delivered with rest of bug fixes as soon as possible.

I will pass you're request Saigon, thank you!

I'm sorry but I do not have any more information myself.
